A thriller at Upton Park comes to an end. After falling 2-0 behind, West Ham stormed back with Andy Carroll scoring an eight-minute hat-trick to put his side ahead before Laurent Koscielny pulled one back.

A point isn't good enough for Arsenal who remain 10 points behind Leicester City having played a game more. West Ham move to within two points of fourth placed Manchester City, but that gap could be six points by the end of the day.

Reid does everything he can to stop Alexis Sanchez breaking away from him on the edge of his own half, including three attempts to foul him. It wasn't as if he had any another choice. The free kick is given, but somehow, there is no yellow card.

Chances at both ends in the space of 30 seconds. Alexis dances through the West Ham defence, jinking into the six yard area and opening up space of the shot. He takes an age, and instead of going for goal, instead decides to cut back inside, running straight into two West Ham defenders. Immediately West Ham pounce on the counter. Payet drives towards the edge of the box and has Carroll making a darting run to his left, but the Frenchman's through ball is overhit.

This game is chaos at the minute. Payet has moved over to the left and is causing havoc. His dancing run into the box allows him to cut back to Antonio, but he can't sort his feet out in time to get a strike away.

Arsenal are level! West Ham fall asleep and Koscielny is able to play a neat one two with Welbeck on the edge of the six yard area and the centre half is free on the return to hammer into the roof of the net.

Arsenal will be 11 points behind Leicester City having played a game more, unless they can turn things around here. West Ham look the more likely to score next, however, Arsene Wenger's side are terrified every time a cross comes into the box.

West Ham close to a fourth! Payet whips an absolutely superb ball in from the right that just evades Antonio near the post. Carroll follows it up but can't get any control on the ball and lifts one over the bar.

Carroll has a hat-trick! What a comeback from West Ham. Antonio does brilliantly down the right and digs out a superb cross for the backpost. He easily beats his marker and his header takes a slight nick of Gabriel before finding the back of the net. An eight minute hat-trick from Carroll, incredible.

West Ham have ball in the net again! Koscielny gets in front of Carroll and tries to prod the ball back to Ospina, but Payet nips in and slots it underneath the goalkeeper! Carroll however was all over the Arsenal defender there, hauling him down in the process. Good call from the ref.

Gabriel is left in a heap following an aerial challenge with Carroll. The West Ham striker is already booked, but escapes picking up another one, despite his elbow catching the Arsenal defending square in the mush.
